Operating voltage: 3.3V/5V. By connecting two electrodes to two fingers with one hand, this strong emotion can be detected.
A method for measuring skin conductance. It can be used to reflect human emotional activities. When people experience emotional stress or have strong facial expressions, sympathetic activity increases and promotes the secretion of sweat glands, thereby enhancing the conductivity of the skin.
This is an interesting device that can create projects related to emotions, such as sleep quality monitoring. This scientific principle is also applied in some electronic skin response devices, such as lie detectors.
